We have some reason to fear, that although all this will be readily admitted in theory, it will be found somewhat difficult to adopt it in practice. The reason of this will be obvious when we reflect on the deep interest which the best and most philanthropic individuals in society take in this science. The other sciences are in some measure removed from the busy pursuits of life; they are the concern of certain persons, who are allowed to investigate and to experiment, to judge and to decide as they please, without the public in general caring much about the matter.--But education is a science of a different kind. Its value is acknowledged by every one, and its interests are dear to every benevolent heart. The individual who undertakes to examine, and more especially to promulgate, any new principle upon which education rests, will have a harder task to perform, and a severer battle to fight, than the philosopher who attempts to overturn a false conclusion in chemistry, or an erroneous principle in mechanics. Among the learned community, not more than one in a thousand perhaps is personally interested either in mechanics or in chemistry; and few others will enter the lists to oppose that which appears legitimate and fair. The enemies and opponents of the chemical reformer in that case may be zealous and even fierce; but they are few, and he enjoys the sympathy and the countenance of the great majority of those whose countenance is worthy of his regard. But when we calculate the number of those who take an interest in the subject of education, and those who do not, the above numbers will be reversed. Nine hundred and ninety-nine among the educated public will be found who take a real interest in the progress of education, for one who cares nothing about it.
